VALVE.

Application filed August s, 1921. serial no. 490x148.

To allwwm'tmag/ concern.' Y

kBe it known that l, ROBERT H. W'ENTORF, a citizen of the United States, residing at Test Bend, in the county of Washington and VState of Wisconsin, have invented certain new andl useful Improvements in Valves, of which the following is a specilication.

Theinvention relates to steam valves, andy has for its primary Aobject the provision of an escape valve' for the steam from steam tight cooking vessels, such, -for instance, as boilers. y n

A further `object of the invention is to provide a valve that will be simple and positive in its operation. l d

A further object ofthe invention is to provide a valve that will be simple in construction and economical of manufacture.

Other objects of the invention will appear fromthe following description, which is directed to the preferred embodiment of the invention, reference being had to the accompanying drawings, forming a part of the specification and in which:

Fig. 1 is a perspective view of a boiler, the boiler proper being shown in dotted lines, showing my improved valve therein in full lines.

Fig. 2 is a fragmental section of the cover, showing my improved valve in plan view.

Fig. 3 is a vertical section taken on line 3-3 of Fig. 1.

Fig. 1 is a vertical section 1-4 of Fig. 2.

taken on line Referencecharacter A ,represents the from the material forming the cover and which are tapered downwardly or toward cally opposite portions thereof, thus form* king cams 18, which provides a depression 19 between the cams 18, in which bar V10` is adapted to lie when the valve is in open from cover 13, thereby releasing washer 16 from contact with the innerface of cover 13, and opening port 12 to allow the escape of steam therethrough. Y By rotating bar 10 about the axis of pin 11 to a position at right angles to the position just described and causing the ends of vbar 10 to move upwardly on cams 18 tothe crowns thereof, pin 11 will be drawn VVoutwardly-of cover 13 andthereby close port 12 with washer16 and head 15. The washer 16 may, if desired, be dispensed with ,and the closure Aof port 12 be accomplished by the forcing thereagainst of head 15. washer 16 may be formed of any suitable material,though, for the purposes of illus tration,-l have shown it as formed of metal. Head 15 of Vpin 11, when forced into contact with washer 16, will prevent thepassage of steam between pin 11 and the washer 16, should there become any play therebetween due to usage.

Bar 10 may be moved to any position intermediate the depression 19 and the crowns of cams 18 for the purpose of partially opening the valve, thereby limiting the escape of steam from the boiler to such extent as may beV desired.

Bar 10 carries linger gripsv20 for grasping with the fingers to rotateI the'bar.

Having thus described my invention, what l claim is:

1. In combination with the cover of a boiler, having a port therethrough, a bar,

'a pin carried by said bar and passing through said port, a head carried by said pin, a washer carried by said pin, and cams formed integrally with said cover and in operative relation to said bar.

2. In combination with the cover of aboiler, having` a port therethrough, a cam on` either side of said port, a bar, a pin carried by said bar and adapted tol pass through said port, a head carried at the end of said pin, said bar being adapted tov lie between said cams when in one position and The overlie saidcams with its ends when `in vanother position. the outer face ofthe cover 13 at diametri-I` 3. In combination with the cover of a boiler, having a port therethrough and cams concentric therewith, a valve 'comprising a bar, a pin carried by said bar, a head carried by the end of said pin, said pin passing y through said port, said bar being adapted to lie between said cams, when the valve s in openposition, and to overlie. said Gams with itsend's when the valve is in Closed position. d

4f. In combination with the @over of a boiler, having a port therethrouglna valve comprising a bar, a pin carried by said bar, having a head at .one of its ends, said pin passing through said port, a Washer' earried by said pin intermediate said head and the inner face of said cover, cams formed integrally Wit-h said. cover and in operative,`

relation to said bar.

` 5. In combina-tion with the cover off' a boiler, having a port therethrough and cams :adjacent said port. a bar, a pin Carried by said bar and passing through said port, a head carried by said pin, and a Washer carried by said pin intermediate said head and said bar. g

6. In combination with the cover Yof a boiler, having a port therethrough andl cams adjacent said port, a bar, a pin carried byy thereon, a bar., av pin carried bysaid bar and passing through said port, a port closure element carried by said pin, and means for forcing said member into Closing position.

8. In combination Witlrthe Cover of a boiler, having a port therethrough and cams thereon, a bar, a pin carried by said bar and passing through said port, a port Closure member carriedbysaid pin, and cam means for forcing said member into closing position.

9.. The combination` of a boiler cover, having a; port therethrough andeams adjacent and concentric to said port, with a bar, a

pin carried yby said: bar and passingthroughsaid port, a head carried, by theendof said pin, a closure member carried by said` pin and interposed between said head andi the inner Jface of said cover, and means for drawing said pin outwardly. of said cover. In.. testimony whereof- I' have, signed my name to this specioation, in the presence of tivo subscribing witnesses, on thisQQnd day of July, A. D. 1921.
